A celebrated Canadian author who writes about First Nations heritage and culture is defending himself on Twitter after his ancestry was questioned in an Aboriginal Peoples Television Network report Friday.

Boyden has won the Scotiabank Giller Prize and his work was nominated for the Governor General's award. He is a member of the Order of Canada and was an honorary witness at the Truth and Reconciliation Commission.

In his statement, Boyden said that he mistakenly said he was Métis. He wrote that when he called himself Métis, he meant that he was of "mixed blood."

Boyden said he doesn't believe he has ever referred to himself as Mi'kmaq, and speculated that people may have misheard him when he said "Nipmuc," a nation of people based out of Massachusetts.

No evidence

In the APTN article, Barrera described the lengths to which he went to verify Boyden's current account of his ancestry, but couldn't find evidence of either Nipmuc or Ojibway heritage.

Barrera says he looked at a book detailing the history of the Boyden family from 1901 and census records, among other historical documents.

"By working backward from the author Joseph Boyden and forward from Thomas Boyden, the root ancestor, it is difficult to determine where Boyden's father's side links into his claimed Indigenous heritage over roughly the last 170 years," Barrera wrote.

Boyden said he believes his family members may not have spoken about their Indigenous heritage.

"I don't believe anyone should ever be made to feel shame in their identity, or to feel as if they are being prosecuted for speaking up proudly for themselves and for past generations who couldn't or wouldn't," he wrote in the statement.

Those "past generations" include Boyden's uncle, Earl Boyden, who "did know about his roots but chose to publicly outright deny them. This was common practice in the 1940s and 1950s," the author said in his statement.

Barrera reported that Earl Boyden "went by the alias 'Injun Joe' and wore a headdress while selling drums made of tin cans wrapped in birch."

But in a 1956 article for Maclean's, Earl Boyden denied actually having any Indigenous heritage, Barrera wrote.
